Appropriate methods to describe materials microstructure are essential for connecting different simulation methods as well as experiments. Focusing on dislocations — the carrier of plastic deformation — we show how continuous field descriptions can be used to represent dislocation microstructure. These fields may be used as input for continuum simulations or for their validation, they allow the comparison of different discrete dislocation dynamics (DDD) implementations, and they are a means of “compressing” the data resulting from DDD simulations. We give an overview of the design choices for D2C, a Python software package designed to convert data from DDD simulations to continuous continuum dislocation dynamics (CDD) fields. The theory beneath each step of this conversion process is outlined.
